Positives: Its a F1 game = Must have.
Negatives: A few bugs and niggles, but some of the new updates have made things a lot better.
Just go for it, it is fun and challenging. There are problems, like the AI don’t crash. Ever. And things like that, and the penalty system is flawed, but I can’t help but enjoy it.

It is a lot better then F1 2010. That game had horrible bugs, including a very weird setup system where 3/1 downforce would be the best at nearly any circuit… You can actually feel the downforce help you in F1 2011, which is nice.
The cars handle a lot better and are more twitchy. The AI is also better, but still not great.

IF you are into proper racing games and racing online it is a must have. Especially if you use a steering wheel and pedals, it transforms the game. I would recommend the Logitech GT wheel which you can get for about £80 which is relatively not too expensive and has good force feedback etc. If you’ve got money to burn, the Logitech G27 is just awesome!

Pros: it’s an F1 game and you can race others online
Cons: penalty system is retarded, career mode gets boring, AI drive like morons and act as if you aren’t there, two patches later and the DRS Zones are still wrong, simple things like the gear ratios lying to you about your top speed.
